UV-Vis (ultraviolet-visible spectroscopy)

UV-Vis spectroscopy is a technique used to analyze substances by shining ultraviolet and visible light through a sample. Molecules absorb specific wavelengths of this light depending on their chemical structures. By measuring how much light is absorbed at various wavelengths, scientists can identify and quantify the presence of particular compounds, determine their concentration, and gain insights into their electronic properties. This method is widely used in chemistry, biology, and materials science for characterizing substances in research, quality control, and environmental analysis.
